Chapter 22, Problem 22.43P

Interpretation Introduction

Interpretation:

The structures compounds $A$ and $B$ is to be predicted. The mechanism of the formation of compounds $A$ and $B$ is to be predicted.

Concept introduction:

Lithium diisopropylamide ($\text{LDA}$) is a sterically hindered strong base. In an unsymmetrical ketone, it abstracts hydrogen from least substituted carbon to form the kinetic product. In a nucleophilic substitution reaction, nucleophile takes the position of leaving the group by attacking the electron-deficient carbon atom.
